Culture
Traffic lights were first installed in London in 1868 (gas-powered) and in the US in 1912 (electric), representing early urban technology that standardized movement in cities.
The metaphorical use of 'green light' (approval) and 'red light' (prohibition) has entered everyday English language beyond driving contexts.
